VT-4

VT-4
The VT-4, also known as the MBT-3000, is a Chinese third generation main battle tank built by Norinco for overseas export.
Development
During the development of Type 90-II/Al-Khalid (also known as MBT-2000) in the 1980s, the gearbox and engine were originally imported from Germany, but this plan was abandoned due to a Western arms embargo. The powertrain instead was sourced from Ukraine, the same for most Chinese export vehicles at the time.
China eventually developed domestic powertrains, which led to the creation of the MBT-3000 program for export customers. MBT-3000 was the successor of the Type-90II (MBT-2000) export tank. The MBT-3000 project later named as VT-4 began development in 2009 as a co-operation with the First Inner Mongolia Machinery Factory and other companies.
The MBT-3000 concept debuted at the 2012 Eurosatory. The tank was subsequently shown at the 2014 Norinco Armour Day and the 10th China International Aviation & Aerospace Exhibition as the VT-4.
Design
The VT-4 shares many subsystems technology and features from other latest Chinese main battle tanks such as Type 96B and Type 99A. Key examples are an automatic transmission system, 125 mm smoothbore cannon, muzzle reference system, FY-4 ERA, carousel-style autoloader, and overall geometry.
Armament
The VT-4 has a 125 mm smoothbore cannon capable of firing APFSDS, HESH, HEAT and HE rounds and guided missiles. There is also a remote controlled weapon station on the turret armed with a 12.7 mm heavy machine gun. The fire-control system has hunter-killer capabilities, laser rangefinder, panoramic sight, and a third-generation thermal imaging system. According to the chief designer, the APFSDS used by VT-4 can reach 700 mm penetration which is enough to penetrate any armoured target, although the distance in which 700 mm of penetration was achieved was not disclosed.
Protection
The tank is protected by dual-layer protection consisting of composite armour and FY-4 explosive reactive armour. According to the chief designer Feng Yibai, the frontal protection force is equivalent to 500 mm homogeneous steel armour, and the explosive reactive armour is around 700 mm. The front turret has wedge-shaped armour similar to other contemporary Chinese MBT's and the hull sides have conventional metal sideskirts. The tank can be equipped with a 'hardkill' active protection system designated GL5, defensive grenade launchers and a laser warning device. The vehicle also has an IFF system, NBC protection, explosion-suppression system, fire-extinguishing system and air conditioning.
Mobility
According to Norinco, the VT-4 uses a locally produced diesel engine with torsion bar suspension and an integrated hydraulic transmission system. Steering and acceleration is handled by a steering wheel and automatic gear transmission. VT-4 is also capable of neutral steering.
Command and control
The tank is also integrated with digital communications systems for tank–tank communication and communication between commanders.

300 VT-4 tanks will be delivered to the Pakistan Army by 2023 along with an option for 160 more in accordance to the 2017 deal.
The Royal Thai Army has 38 VT-4 in service, with the first 28 delivered in October 2017. The deal, thought to be valued at about US$150 million, included an option to buy a further 153 vehicles. In April 2017, the Royal Thai Army ordered an additional 10 VT-4 main battle tanks from Norico worth US$58 million that was delivered as of early 2019.
